Hi,
I use PD for audio performance all the time and I run into audio stutters/dropouts regularly, but not always. It's a little unpredictable. Sometimes they happen because of GUI processes, sometimes they happen because of audio file reading/hard drive activity. I'm using readsf~ to play audio files, and when i load a new file sometimes i get a dropout and sometimes i don't... same thing for loading abstractions and opening/closing patch windows.
I'm not sure how to resolve this.. running in -rt mode used to help, but i'm running on os x and -rt mode doesn't exist any more. I'm not really sure what to do about these problems, but the more I play live the less acceptable they are.

i just wanted to poll the users out there about thier experience with audio stutters and glitches caused by the pd gui. I'm working on a realitime performance environment and am banking on being able to instantiate objects, popup new windows and general edit patches live, with audio processing going on. i havnt gotten my ALSA all tightly configured yet, so i havnt been able to do some hardcore testing yet, so I was interested in how things are going for all of you. with your setup, if you popup abstraction windows, does audio skip/stutter? A) never B) sometimes C) always.
if need be i'll run to pd processes to avoid the skips, one being a -nogui audio process niced to -20, the other being a -noaudi gui front end to control the audio. if i can, i'd like to avoid this since it will complicate the system a lot.
do you have tips for how to improve the performance?
i'd appricaite any info you have about your rig, thanks!
